To all 10. mm it m-ay concern.

Be-it known thatI, LEO A. GORDON, a

I citizen of the United States, and a resident of Fall River, in thecounty of Bristol and State of Massachusetts,.ha\-'e invented a new and useful Improvement in Demountable Rims, of which the following is a specifica 'tion.

My invention is an improvement in deinountablc rims, and has for its object to provide a rim of the character specified, especially adapted for use in vehicle wheels 'having'pneumatic tires for permitting the Fig. 1, Fig; 3 is a section on the line 33 of Fig. 1., Fig. 4 is a top plan View of one of the clamping elements, Fig. 5 is a section on the line 55 of Fig. 4, Figfi'isa top plan View of the clamping bolt, and F ig- 7 isvaview similar, to Fig. 1 showing theinvention in connection with a rim-0f the quickly separable type.

The present embodiment of the invention is shown in connection with a wheel having a telly 1 of wood, connected to the huh not shown, by spokes An ordinary clencher t we rim is mounted on the fell; the said rim having at each side edge a lateral flange 4, whose extremitj. overlies the loo-fly of the rim as shown at 5. r

T casing tof the pneumatic tire is shown in connection with a rim 7 of the clencher type, the said rim having at; each edge a lateral flange'S, provided at its extremity with a portion 9-overlying the body of the rini. and the said rim 7 is of greater diameter than the rim 3, so that it may be "a wheel coaXialWi-th the said paced relation. The run .irnilar to the rim 3 with arranged on t rim 3 in ra 7 is in all 1 this excep l r The casing 6 ot-the pneumatic tire is provided with as usual ribs 10, at its side edges and on the outer surface of the casin Specification of Letters Patent.
